Here are some explanations of surface tension:
- Surface tension is a property of the surface of a liquid that causes it to behave as an elastic sheet. It allows insects, such as the water strider (pond skater, UK), to walk on water too. It allows small objects, even metal ones such as needles, razor blades, or foil fragments, to float on the surface of water, and it is the cause of capillary action.
- 5.18 pounds / feet at 0 degree Celsius. Or as I remember it is 72 dyne / centimeter at 25 degree Celsius. The surface tension of water is the force required in order to float at the water's surface, hence making water to behave like an elastic sheet.
- Water surface tension is contractive tendency of the surface of a liquid that allows it to resist an external force. The beading of water on a waxy surface, such as a leaf, is an example of water surface tension.

∙ 8y agoSurface tension is produced at the boundary between a liquid (not just water) and air. It is caused because within the liquid the molecules are equally attracted in all directions by other molecules of the same liquid, but at the boundary they are only attracted in the direction of the liquid not in the direction of the air. The balanced attraction of liquid molecules exactly in the plane of the boundary creates the actual tension on the liquid surface.

The pull on the surface of the liquids that allow liquids to form drops when they fall?
It is surface tension.
Why does dawn dish soap repel pepper?
Soap breaks the surface tension of water. Pepper will only float where there is strong surface tension.
What attraction is important to water striders?
Surface tension is important to water striders because surface tension gives them the ability to float and not sink and drown.
Are wind-driven currents near the surface or in the deep waters?
Vertically
The unit of surface tension is?
Surface tension is basically a force acting on the surface of a fluid.so the units will be newtons(N) and dimensions are MLT-2But generally we talk in terms of surface tension coefficients which is surface tension per unit length.Vishesh MadanSurface tension is perpendicular force acting per uint length of an imaginary line stretched on the surface of a liquid. Therefore, SI units will be N/m, since the value of surface tension for all liquids is very low therefore it is commonly mentioned as mN/m. Dimensions formula for surface tension will be MT-2.In another case Surface tension is also measured as work done to streach a unit surface area of a film, in that case units will be J/m2.K Singh
Is soap the only substance that can break the waters surface tension?
detergents and water striders can also do that.
What reaction produces a floating film on waters surface?
It's not a reaction, it is either the difference in density or the effect of the surface tension of the water
What physical traits are attributed to waters polar nature?
Solvent potential, cohesion, adhesion, high surface tension
What is the difference between buoyancy and water surface tension?
Buoyancy is the force exerted by the weight of water displaced by an object that is at least partially submerged in the water. Surface tension a force of attraction exerted between water molecules at the waters surface interface. Something can not become submerged in the water until this surface tension is broken. Surface tension is a very weak force and can be overcome physically or by changing the chemistry at the surface (adding a wetting agent).
why water stick insect lives on the surface of the pond?
The insect uses the waters surface tension to walk where others can’t. His only problem comes from below.
What is a force that acts on particles at a liquids surface?
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
Surface Tension is found in what?
Surface tension is found in Liquid
What is surface tension coefficient?
define coefficient of surface tension
What liquid have the strongest surface tension?
Mercury is the liquid with the strongest surface tension.
Is the inward force among the molecules of a liquid?
The inward force among the molecules of a liquid is Surface Tension
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
How do you break the surface tension?
Adding surfactants the surface tension decrease.
